Answer: Both marbles will experience an electrostatic force. If they have like charges the force will be repulsive. If they have opposite charges the force will be attractive.
Explanation.
The electrostatic force is the repulsive or attractive force between charged objects.
This are the basic characteristic of electrostatic force:
1) Charged objects will experience electrostatic force..
2) The electrostatic force is proportional to the product of the charges, so both objects will experience the same electrostatic force: the product of their charges.
3) The electrostatic force is inversely related to the square of the distance that separates their center. So, the more separated they are, the weaker the force.
4) If the two objects have the same kind of charge (both positive or both negative) the force will be of repulsion.
5) If the two objects have opposite charge (one positive and the other negative) the electrostatic force will be atttractive.
